Default: any
+nfsrootdebug
+
+ This parameter enables debugging messages to appear in the kernel
+ log at boot time so that administrators can verify that the correct
+ NFS mount options, server address, and root path are passed to the
+ NFS client.
+
+
+rdinit=<executable file>
+
+ To specify which file contains the program that starts system
+ initialization, administrators can use this command line parameter.
+ The default value of this parameter is "/init". If the specified
+ file exists and the kernel can execute it, root filesystem related
+ kernel command line parameters, including `nfsroot=', are ignored.
+
+ A description of the process of mounting the root file system can be
+ found in:
